原创 [PAT][Basic Level Practice]Problem1089
Solution： 已知 N 名玩家中有 2 人扮演狼人角色，有 2 人说的不是实话，有狼人撒谎但并不是所有狼人都在撒谎。要求你找出扮演狼人角色的是哪几号玩家？ ——》 说谎话的人（liar）:一个是狼人（wolf）；一个是好人（man） 如果有解，在一行中按递增顺序输出 2 个狼人的编号，其间以空格分隔，行首尾不得有多余空格。如果解不唯一，则输出最小序列解 —— 即对于两个序列 A=a[1],…,a[M] 和 B=b[1],…,b[M]，若存在 0≤k<M 使得 a[i]=b[i] （i≤k）

int i;for（i=0； ；) 与 for(int i=0 ； ；) 两种定义循环变量的方式的区别： the difference between int i;for(i = 0；；) and for(int i = 0；；): 两种均可，前者i在for循环外部定义，则i的值在程序未结束之前就一直存在，i所占的内存空间直到程序结束时才释放；后者的i在for循环内部定义，则当for循环结束时，i所占的内存空间就被释放了。一般建议用后者的方式，因为当程序较大时，前者更占内存，这样程序在运行时CPU的负担
